Numbers 10:29-34

²⁹And Moses said to Hobab, the son of Raguel, of Midian, his ally, either father of his wife, We go forth to the place which the Lord shall give to us; come thou with us, that we do well to thee, for the Lord hath promised good things to Israel.

³⁰To whom he answered, I shall not go with thee, but I shall turn again into my land, in which I was born.

³¹And Moses said, Do not thou forsake us, for thou knowest in which places we owe to set tents, and thou shalt be our leader;

³²and when thou shalt come with us, whatever thing shall be best of the riches that the Lord shall give to us, we shall give to thee.

³³And therefore they went forth from the hill or mount of the Lord the way of three days; and the ark of the bond of peace of the Lord went before them, by those three days, and purveyed the places of their tents.

³⁴And the cloud of the Lord was upon, or over, them by day, when they went forth.
